Since there are so many mortgage companies now it is rumored that many companies are not letting known mistakes slip to damage credit which prevents the mortgagee from jumping.

I get free appraisals and closings and I can't count how many times I refinanced in the last 4 years.

Call you OLD company and describe the error, get some sort of a fax or email from them the more vague they are the better forward it to the credit reporting agency and that might do it.
